Fig. l1 is a sectional view on the line II--II of Fig. 10. 10

Fig. 12 is a side elevation of Fig. 10.

Referring to Fig. 1, the machine is provided with a suitable base lhaving upright standards 2 and 2B. A rod 3 lis suitably mounted in thesestandards. 15

AnA operating arm 4 is provided with a collar 5, which is turnablymounted upon the rod 3. The rod 3 is provided withcollars 6 and 6, whichare secured to said rod 3, so as to prevent any lateral movement ofthecollar 5.

As shown in Figs. 1 and 4, links 'I and 'IA are I provided with pins Pbwhich are located in slots or holes of the operating arm 4. When the arm4 is turned downwardly, said links 'I andl are also moved downwardly.The links l and 1n are pivotally connected at their lower ends to'- alug 8 of a block 9, which is guided for vertical movement by means ofupright rods I0 and Ille, whose lower ends are suitably connected to a36 plate II, which is suitably connected to the base I. The plate Il isconnected to the base I byy Ameans of bolts I2.

Top dies I4 and I6 are suitably connected'to the undersideA of thevertically movable plate 9, by means of screws I5. Additional means areprovided to guide the up and down vertical movement of the plate 9.

As shown in Fig. 1, this plate 9 has a general rectangular contour. 4Referring to Fig. 2, -each lateral face of the plate 9 is provided withlinks I1, whose lower ends are pivotally connected to said lateral face.At their upper ends each said pair of links I9 is connected to a commonpivot member 20 and said 45 pivot member 2li is connected to an arm 2lby means of a nut 22.

'I'here is a slight lost motion between, pivot members 20 and arms 2l,in order to permit the arms 2| to turn'whle the plate 9 moves in avertical path.

connected by a tie-rod 24.

As shown in Figs. 2 and 4, the upper die I5 is provided with a soliddepending flange 25.

In this particular embodiment the die Id and its depending flange 25 areof circular contour but I do not wish to be limited to any particularshape.

As shown in Fig. 4, the die'Il is provided with a recess 26 in its lowerface and said recess is of annular shape and it surrounds the dependingflange 25. l The die I4 cooperates with a lower die 21 whose bottom faceis provided with a downwardly projecting neck 34, which is located in acorresponding recess of a block 28, which rests upon the base I.

As shown in Fig. 4, the plate I I is provided with a tongue which entersa groove in the block 28, so that the block 28 is slidably held inposition at one side. At its other side the block 28 is held in positionby means of a clamping member 29 which is secured to the base I by meansof bolts 30. A head 3I is clamped to the member 29 by means of bolts 32,and said head 3i overlies one side of the block 28, and clamps that sideagainst the base I. The lower die 21 can be connected to the block 28 bymeans of a drive t or by any other suitable means.

As shown in Fig. 4, the lower die 21 is provided with a centralcup-shaped recess 33, which is of circular contour, in this particularembodiment.

Likewise, and as shown in Fig. 4, the lower die 21 is provided with anupstanding annular shoulder 35.

As shown in Figs. 3 and 4, this annular shoulder 35 is provided with aseries of concentric grooves G, said grooves being of V-shapedcross-section.

In order to utilize the dies It and 21, a sheet of the material isplaced upon the shoulder 35 of the lower die 1. The arm d is now pulleddown, so as to move the die Ififrcm the position shown in Fig. 2, to theposition shown in Fig. Il. The flange 25 first engages the material andsaid fiange 25 initially forces the central part of the sheet ofmaterial Minto the recess 35 of the lower die 21. The lower annular faceof the upper die I5 then clamps the edge of the material against a partof the annular shoulder 35 of the lower die 21.

The dies I4 and 21 are made of hardened steel, so that they operate likea pair of punches to cut olf the superfluous edge part of the material.

The effect of forcing the central part of the sheet of material into therecess 35, is to form partial plaits in the upstanding wall of thecupshaped member which is thus formed. Such partial plaits are alsoformed in the top flange of said cub-shaped member.

The inner edge of the annular bottom face o the upper die I5 cooperateswith the adjacent groove G, in order to cut or trim the edge of thepiece of material M.

The effect of the operation of the dies I4 and 21, is to produce theblank B which is shown in Fig. 8. Fig. 8 shows the partial plaits P inthe upstanding Wall of the blank B, and it also shows the plaits Pawhich have been formed in the ange of said blank B. As shown in Fig. 7,the plaits P radiate outwardly. The lower die 21 is longitudinallyshiftable, so that it can cooperate with the second die IS.

As shown in Fig. 3, the block 2S is of of general rectangular contour,save that one lateral face thereof is provided with a groove 4G. 'Ihisgroove 4G is located intermediate the top and bottom faces of said block28, and it has the tapered shape which is indicated by the line 4I inFig. 3. A link 42 has its end located within said groove 4t, and theinner end of said link 42 is pivotally connected by means of a pin 43 tfthe die 21. The outer end of the link 42 is pivotally connected at lidto a lever 45, which is pivotally connected to the base I, by means of apin 46. When the lever 5 45 is in the full line position shown in Fig.3, the die 21 is underneath the die I4. When the lever 45 has beenshifted to the dotted line position shown in Fig. 3, the plate 28 andthe die 21 have been shifted to the dotted line position shown 10 inFig. 3, which is underneath the die I6. When it is necessary to shiftplate 28, the clamping means 3B and 32 are loosened.

Adjustable stops 41 and 48 are provided for limiting the longitudinalmovement of the block 28 15 and the die 21. The upper die I8 is providedwith an electrical heater H of any suitable type.

As shown in Fig. 5, the underside of the die I6 is provided with anannular shoulder having grooves which correspond to the previouslymentioned grooves G. Hence when the die I6 is yforced into the `positionshown in Fig. 5, its

grooves mesh with said grooves G so that the V- shaped ridges which areformed intermedate the grooves G, and these ridges enter thecorresponding V-shaped depressions which are provided at the bottom faceof the die I6. The effect of this is to form circular corrugations 49 inthe blank B- and the walls of these corrugations have portions of morethan one thickness, corresponding to the plaits Pa.

Prior to utilizing the die I6, the blank B can have the material placedtherein, and a cover piece 5U is placed over the flange of the blank B.The eiect of the heat and pressure which is exerted by the die I6, when"Cellophane is utilized, is to shape the cover member 50, and to providecircular corrugations therein, which intermesh with the corrugations 49formed in the fiange of the blank B.

Fig. l0 shows the corrugations ifia which are formed in the cover member50.

Fig. 6 shows the grooves Ga which are formed in the annular anddownwardly projecting portion of the die I6. The heater H is providedwith leads L.

As shown in Fig. 3, the standards 2 are bolted to angle members G whichare connected to the base I by means of bolts 6I.

While I have shown numerous specific details and improvements, theinvention is not to be limited thereto, as it generally covers a machineand/or method of rst shaping a flat sheet of material into a cup-shapedblank having a flange and then connecting a cover to said flange,preferably by means of interlocking corrugations.

Whenever I specify the formation of a cupshaped blank, I do not Wish tobe limited to any particular shape, as cup-shaped is intended to coverany form or shape of hollow container. 60

For convenience I prefer to describe the die 21 as a lower die, and todescribe the dies I4 and I6 as -upper dies. However, the invention isnot to be limited to a .machine in which the superposed relation ismaintained. Likewise, while I have shown continuous grooves in the topsurface of the lower die, and in the bottom surface of the upper die I6,I do not wish to be limited to such continuous grooves,` since theinvention vgenerally covers the idea of embossing or otherand the termgrooves generally covers Ione or 75 more cooperating pairs ofdepressions and projections which emboss the flange of the blank and itscover.

I have shown a preferred embodiment of my invention, but it is clearthat numerous changes and omissions could be made without departing fromits spirit.

I claim:

1. Mechanism for forming acontainer, com-- prising a lower die having arecess, the top surface of said die adjacent the top of said recesshaving a plurality of grooves, and an upper die having a recess aroundsaid top surface, said upper die having a lower surface which contactswith said grooved surface of the lower die, said lower surface beingspaced from recess of the lower die when such contact is made.
